SWB-2817, 16x22, 0.3 A, Reed Matrix Module for SwitchBlock
781420-17
Relay Matrix Module
16x22, 0.3 A, Reed Matrix Module for SwitchBlock - The SWB‑2817 is a reed relay matrix module for SwitchBlock systems. Designed for high power, it can operate as an individual relay card or expand in a single carrier or single PXI chassis. You can connect any input to any output, individually or in combination. You can use matrix switches to route signals from oscilloscopes, DMMs, arbitrary waveform generators, and power supplies to various test points on a unit under test (UUT). The primary benefit of matrix switches is simplified wiring—the overall test system can easily and dynamically change the internal connection path without any external manual intervention.

PXI Relay Module
Relay
PXI Relay Modules consist of multiple independent relays, such as single-pole single-throw (SPST), single-pole double-throw (SPDT), and double-pole double-throw (DPDT) relays. PXI Relay Modules use a variety of relay types, including electromechanical armature relays, reed relays, field-effect transistor (FET) relays, and solid-state relays, each with their own benefits, allowing you to choose a set of relays that fit your requirements. To program the relays, you can use the IVI-compliant NI-SWITCH driver software, complete with help documentation, example programs, and a soft front panel application for interactive control. For intelligent management of complex switch systems, NI Switch Executive provides additional software tools to help you design, build, and deploy your switching system.
